GLASS-WORKING MACHINE:

Original application filed July 127, 1922', Serial No! 577,792.

1924. Serial No.3685,'151'.;'

though not necessarily limited to such use:

This. application is a division from my pendingaapplication Serial. Number 577,792.

The accompanying drawings illustrate my;

invention. Fig. 1 is a general :view in parmatic; of my improved apparatus; Fig. 2 a plan of a satisfactory form of shearlng mechanism; Fig. 3 apartlal llOI'lZOIlllfLl section of-the shears Fig.4 a partial vertical sectionof the compactinig head mechanism; Fig. 5 a fragmentary vertical section of some n of the parts shownin Fig.4 in another pow sition';; Fig. 6 a plan in partial horizontal section of i the compacting: head mechanismin compacting position; Fig. 7 a plan of the parts shown in Fig.- 6 in withdrawn positiom and Fig. 8 a fragmentary detail of the funnel and its carrier.-

In the drawings lO indicates the'delivery spout of a glass furnace having a downwardly directed delivery orifice 11 through which a. stream of glassis delivered; being controlled conveniently by means of a vertical-ly reciprocating plunger 12. Located in a horizontal plane slightly below-the lower end of discharge orifice 11 is a pair of cutting blades 60 whichmaybe of any desirable and well-known type. although I prefer that they be of such character as to move toward each other so as to complete their cutting function substantially at the axis of a column of glass issuing from the discharge orifice. 'these shears are shown as being manipulated by means of a pneumatic motor 6 1, the

action of which is controlled by a controlling valve 62 operated by a timing element 54 which is constantly driven and serves, through a pitman 55, to reciprocate a tabledriving element 56 of well-known form to advance a. mold-carrying table 57 step-bystep. The details of these mechanisms form no part of mv present invention. and may be of any well-known and desired form.

Located in line below the orifice 11 is a funnel 70. vertically reciprocable by means of a cylinder and piston structure 7 2 of common type and connected by suitable piping tial vertical section,-- and partially diagram:

with a control valve 73farranged within the influence of timer. 54, the arrangement being; f

such that the funnel will be intermittently 7 raisediand lowered so-as to co-operateiwith successive pla'inmolds75 brought; successive.- ly into :filling position by advancement of the mold-carrying table 57.-

fill

The precise details of the. moldrearrying table 76 and the mold 75 are wholly im-,-

material so far as the present-invention is concerned. Anyof the well-knowntypes of machines .embodyingua movable carrier ifor? a series-ofmolds to 'be carried throughs a successive series of positions for filling;

formingg'eta. may be utilized.

In order thatthe fresh charge of glass maybe compacted. into theelower portion ofv the mold (the'neck. portion, of .theumolddn a narrow neckbottle machine\; I have con: slderedut advisable to provide a construe t-ionby means of which the compactingmay be accomplished as quickly as possible-after the charge of glass. has been dropped into the mold. and consequently I have provided a compacting blow head 81 arranged to oper-.

ate 'at the filling statioru thus eliminating theperiod which is commonly required for wherein a vertically sliding; lower.

acts as a valve to controlair flowz When the compacting head 81 1s arranged -Head 81'is shown-as of a common type portion.

at the filling station it is of course necessary of the rod of which is attached a finger 86 I which is slidably mounted on pin 83 and interdigitated with lever 82. The bell crank 82 has one of its arms slotted at 87 to receive a pin 88 carried by rod 89 of piston 90 which is mounted in the cylinder 91.

Pin 88 is arranged verticallv and has sufiicient length to permit a vertical movement of the lever 82 and said lever slides alongside a post 92 which is of such height that, when lever 82 is raised to its highest position, so as to lift head 81 from contact with the upper end of funnel 70, lever 82 may be swung upon 83 so as to bring one of its arms over the top of post 92 and thus prevent accidental dropping of the head 81.

The movements of pistons 85 and '90 must be properly co-ordinated and for that purpose cylinder 84 is provided with a bottom port 100, top port 101 and intermediate port been driven to its final position to bring head 81 to glasscompacting position.

Ports 103 and 100 are connected by suitable pipes 103 and 100, respectively, with a control valve 106 arranged within the influence of the timer 54; Ports 105 and 101 are connected by Japipe105 and ports 102 and 104 are connected by a pipe 102 the arrangement being such that when air is admitted through port 103, piston'90 will be driven to the position shown in Fig. 6 and thereupon air may flow from port 105 through pipe 105' to port 101 and thus drive piston 85 to a position shown in Fig. 4 whereupon air may pass through port 102 and pipe 102 to port 104. In the meantime, however, the air supply from valve 106 to port 103 has been cut off and there istherefore no return movement of piston 90. In'

pipe 102" to port104 and thus cause a re turn of piston 90 to the righthand end (Fig.

6) of cylinder 91.-

The shear and plunger movements are so co-ordinated, in awell-knownm'ann'er, preferably as set forth in my above-mentioned application, to deliver successive passages of molten glass to funnel 7 0 whereupon the tunnel and compacting head, or blow-head,

piston unit connected to said blow-head-support, to produce vertical movement thereof, a cylinder-and-piston unit connected to said blow-head-support to produce swinging movement thereof, supply pipes leading to said two cylinder-and-piston units, means for controllingflowof motive fluid therethrough, and intermediate connections between the two cylinders and controlled by the relative movement of their pistons whereby successive lateral and vertical movements of the blow-head are obtained.

2. In a glass working machine, the combination of an element movable: in two directions, a pair of cylinder-and-piston units connected to said element, each to cause movement of the element in one of its directions, means for controlling the flow of motive fluid from a source of supply directly units, and a pair of independent motive fluid connections, each between an mtermedlate 'point in one cylinder'and the, opposite end of the other cylinder, whereby relative move- "ment bet-ween each piston and its cylinder 'will control flow of motive fluid to an end of the companion cylinder.

In witness whereof, I, Alexander Samuelson, have hereunto set my hand at Terre Haute, Indiana, this 5th day otJanuary,
